If you like to test new features, you can participate in the test program: https://play.google.com/apps/testing/eu.faircode.netguard

All required permissions are described here: https://github.com/M66B/NetGuard/blob/master/FAQ.md#user-content-faq42

NetGuard uses the Android VPNService to route traffic to itself, so it can be filtered on-device instead of on a server. Only one app can use this service at the same time, which is a limitation of Android.

Works good but on my phone it seems to lose the apps randomly and a refresh usally doesnt help. Even a phone restart usally doesnt work. Usally they do seem to randomly reappear. I dont have the pro version. Would be perfect if there was some way to be able to use a VPN at the same time. I think that is an android problem though.

Your problem is caused by a bug in your Android version, Allen. The app list is coming from Android! Given the time I have put into this project to help you protect your privacy, a 2* rating for this reason is therefore rather disappointing. Please reconsider. You can always contact me for support as well.

Thus far, the app is excellent. You do need to spend a few minutes on the setup. I would also like to know if Netguard is willing to give a small discount on PRO version, as I am semi-retired and do a mass of pro Bono work, and my monthly bill for Apps, internet, telephones, and miscellaneous is staggering. In closing, I repeat that the app is top notch.

This is a very nice application. It takes very little space, and it blocks all kinds of Internet traffic. There is so much internet traffic, that both goes out and comes in! This can capture it. Plus, you don't need access to the root directory/folder, or the top level folder, to make this work. It is so nice ( : Suggest getting the registered version. Encourage the developer. This stuff takes a lot of work!! Thank you for this awesome application, Mr. Developer, lol
